Sir Anthony James Leggett KBE FRS (26 March 1938 – 8 March 2026) was a British theoretical physicist. He was a professor emeritus at the University of Illinois at Urbana-Champaign. Leggett was known for his theory of low-temperature physics. He won the 2003 Nobel Prize in Physics.

From 2006 to 2016, he worked at the Institute for Quantum Computing in Waterloo, Ontario. He was chief scientist at the Institute for Condensed Matter Theory, a research institute at the UIUC.

His research focused on cuprate superconductivity, superfluidity in atomic gases, low temperatures of amorphous solids, the formulation of quantum mechanics and topological quantum computation.

Leggett died on 8 March 2026 at the age of 87.
